.To all 'ie/om it may concern:

Be it known that l, :hinun'r ll. Sunni.. a

citizen oi the United States. and a resident i is declared to be,

of lilaywood, county oi' Cook, and State of illinois, have inventedcertain new and use-H` ful improvements 1n tanopyllolders tor,

Lighting-Fixtures, of which' `the following.;

a full, clear. and c yact description.

This invention relates to canopy holders for lighting fixtures. and itsprincipal ob ject is to provide a holder capable of hohling-seyeralsizes of canopies inr iixed relation to the ceiling or other object towhich thc lighting fixture is attached. y

Another object is to provide a holder which `may be quickly and easilysecured in place, and to which or from which the can` opy may be readilyattached or detached.

lilith these, and other objects in View, 'this invention consists in theseveral novel iieatures of construction, arrangement and combination ofparts, which are fully set forth and claimed in the followingspecification.

.i The invention is el arly illustrated in the` accompanying drawing, inwhich :w

Figure 1, 1s a View partly 1n suie elevation and partly 1n central,vertical section oi a canopy holder embodying: simple form o1" thepresent invention; Fig. 2. 1s a horizontal section talcenion line 9:-2ofilig. 1; l `ig. 3, is a perspective View of the canopy holder and Fig.is a sido elevation. partly broken away, of a. slightly modified form oithe inyention. e

l.itei'errmg to sind drawing, 5, designates the ceiling or Wall oi aroom. upon which is supported a box (5, baring one or more. openings 7,through which ext-ends one end of the wire containing conduit 8. plug 9,having a screw-'threaded nec-l 10, formed therion, is bolted to the box`il. in the usual and well-known manner. The canopy holder 11, is madeof, two holding inembers 12, 13, attaohably and detaehably connectedtogether. The upper oi Vbase member 12, comprises n.. tlat base portionlli., from the two ends oi' which project two parallel downwardlextending arms 15, 15, the side edges of which, through a. portion of'their extent. are heut back upon themselves as clearly seen at 1G inFigs. 2 and to form guideways for the reception of certain arms thelower holding member 13. The base 1l. hasI a centrally locatedscrew-threaded hole ii'. whereby thc holder may be screwed upon thescrew-threaded neck ot' the plug Si. To the inner sides of the arms 15,are riveted or otherwise. secured two hooks or detents 18. the taperedends of which project through holes 12'), formed in the arms 15; saidhooks or detents are made of elastic material. and are arranged to pressoutward through said holes if).

'l`he lower canopy holding member 13, has a criiss. ere Q0. formed witha centrally located aperture 21, and at the ends` ot' said erosspiece,said member 13. is formed with two up 'ardly extending parallel arms 22,fitting' in and slidably held in said guideways 1G. by the hooks ordetents 1S. which project through holes Q3, that arc formed in saidarms22. The holes Q3, are arranged in line with the holes` 19. so that whenthe arms hare slid up in. the guideways 16. Ythe hooks 1S. may springihto the holes` Q3. land retain the lower canopy holding member in placeon the upper one.

The canopy A, is of' the usual form employed to cover the wireconnections and box (i. and has a central opening through which theconductor cords :24. exten'd down to the soclget A bushing 26, formed ofnou-conducting material surrounds the con` doctor cords and has ascrew-threaded neck or reduced portion 27. which screws into the hole2l, in the lovyer, canopyholding mem ber 13. A strip'of liber or othernonwonducting material 28. is interposed between the bottom ot' saidmember 13. and the can` opy si, to gua therebetween.

ln use. the holoer is screwed upon the plug .9. the conductor drop eords:20. inserted through the hole 21. and the connections made with thehouse wire. 'lhe lower canopy holding member lil. should be adjusted asfar down as found necessary to accommodate the canopy. The liber stripQS. eanopy and bushing 2li.. are then slipped over the conductor cordsand the canopy' pushed up against the lower holding member until theupper edge oi the canopy seats against the 4ceiling. blt this time thehooks 18, should enter t-w-o` holes Q3. in the arms Q2, therebypositively connecting the two niembers 1i?, 13, but it may happen thatthe arms Q2. stop with the protruding ends of the hooks /standing/intermediate two adjacent pairs of holes In this event the bushing 2G,when screwed home against the bottom ot' the canopy, acts to draw thelower holding member back far enough to bring the, next adjacent holesin the arms 22, into register with the hooks7 whereupon they snap intothe holes 23, and rigidly connect to- .pulled down'and the hooksreplaced in the holes 1S); the parts are then ready for reassembling.

ln Athe modilied l'orm illustrated in Fig. Al,

1 a ceiling light 1s shown. lhe canopy A is interposed between a shadeor globe holder and the ceilingl 5PM The globe holder hasan `end piecee. which lits against the, crosspiecey 20L ot the lower holding memberlf3 and is secured thereto by screws 20, which pass through bushings'2(3. lormed ol liber or other non-conducting material, and are threadedin the crosspiece E20, of the lower holding member llk A strip of fibeor other non-conducting material interposed between said member lil, andend piece n, of the shadefholder prevents a short-circuit between thecanopy holder and shade support.

More or less variation of the exact details oi construction shown anddescribed is possible without departing from the. spirit of thisinvention. l desire, therelorc, not to limit myself to the. exact formsot construction shown and described. but intend in the i'ollowing claimsto point out all of the invention disclosed herein,

I claim as new and desire to secure by Letters Patent l. A canopy holdercomprising two canopy holding members. each having lengthlwise extendingparallel arms, slidably secured to the arms o]e the other memben thearms of one member having rows of perlorations and the arms ot' theother member having hooks adapted to enter said periorations. one olsaid members having an internally screw-tlireaded end piece adapted forattachment to a. supporting plug, and the other member heilig arrangedto abut against a canopy, and a threaded connection for clamping thecanopy against the lower canopy holding member.

2. A canopy holder comprising an upper and a lower canopy holdingmember` the one being formed with guideways, and the other with armssliding in said guideways, said last mentioned arms having rows ofperforations, hooks on the first mentioned arms adapted to enter saidperforations, one ot' said members being formed with means forattachment to a support7 and a clamping element I'or securing a canopyto the other member.

A canopyv holder, comprising an upper holding member haring; aninternally screwthreaded base portion and tivo parallel arms extendingtl1(-\ie'troiii. said arms being formed with guideways. and there beinghooks secured to said arms. a lower holding member. having alcrosspiece. formed with two parallel arms extending therefrom andslidably guided in said guidewavs, each of said arms having a lengthwiseextending row oic perforations into which a hook enters. and canopyclamping means engaging with said lower holding 1nember.

`vl. A canopy holder cmnprising` an upper holding member. having aninternally screw-tln'eaded base portion and two paral- `lel armsextending therefrom, the side edges ot' which are bent back uponthemselves to lorm guidewavs. av lower holding member having acrosspiece and two parallel arms slidably guided in said guideways,elastic hooks secured to the arms of'one holding member and adapted tosnap into holes formed in the arms of the other member, and canopyclamping means threaded in said crosspiece, for clamping a canopyagainst said crosspicee.

canopy holder comprising an upper holding member having an internally7screwthreaded base portion and two parallel arms extending therefrom,the side edges of which are bent back upon themselves te forniguideways` a lower holding member having a crosspieee and two parallelarms slidably guided in said guideways, spring hooks secured to the armsof the upper holding member and arranged Ato snap into holes which areformed in the arms of the lower holding member. said holes beingarranged in rows extending lengthwise of the arms, and a bushingthreaded in the erosspiece of the. lower holding` member and arranged toclamp a canopy against said erosspieee.
